Background technology
In low-pressure mercury vapor type discharge lamp, mercury has consisted of the element of generation ultraviolet (UV) radiation.The inwall that the fluorescence coating that comprises fluorescent material (for example fluorescent material) may be present in discharge cavity converts ultra-violet radiation to the radiation of other wavelength, for example converts UV-B and UV-A radiation to or converts visible radiation to for common illumination purpose for tanned purpose.Therefore this discharge lamp also is known as fluorescent lamp.Replacedly, the ultraviolet light of generation can be used to make bactericidal lamp (UV-C).The discharge cavity of low-pressure mercury vapor type discharge lamp is normally circular, comprises simultaneously the embodiment of elongation type and compact.Generally speaking, the tubular discharge chamber of compact fluorescent lamp comprises the set that relatively short straight shaped part with less diameter is divided, and wherein straight shaped part is divided by bridge portion or sweep and is connected to each other together.The device of sustain discharge is the electrode that arranges in discharge space in discharge space.Also can use outer electrode.Outer electrode can be the conductive coatings in the discharge cavity end parts.Conductive coatings is as capacitive electrode, and when lamp was worked, the wheelbase that discharges therebetween between outer electrode extended.
Low-pressure mercury vapor discharge germicidal lamps mainly produces the UV-C radiation, and such lamp is used for the sterilization of water and air, food sterilization, the curing of ink and coating, the destruction of pollutant in the water and air.The main radiation that produces in this lamp has the wavelength of 254nm, and it can stop, for example the growth of mould and bacterium.
Mercury vapor pressure has a strong impact on the work of low-pressure mercury vapor discharge (sterilization) lamp.For effective work of lamp, need to preset the scope of mercury vapor pressure in the discharge cavity.By using a kind of mercury alloy, can in relatively wide temperature range, mercury vapor pressure be controlled in this predefined scope, thereby allow expeditiously operating light, and relatively high radiant output in this temperature range that allows to bring thus.In description of the invention and claims, the address " optimum temperature range " that is used for mercury alloy refers to a temperature range, in this temperature range, mercury vapor pressure namely is under the optimum condition of work at mercury vapor pressure so that the radiant output of lamp is 90% of greatest irradiation output at least.The definitions of efficiency of lamp is that the power output of UV-C is divided by the lamp input power.The International Patent Application WO 2004/089429A2 that announces discloses a kind of low-pressure mercury vapor discharge germicidal lamps, and mercury alloy is positioned at the end parts of lamp, allows in a relatively wide temperature range effectively operating light.Yet under given conditions, temperature perhaps can change in one way and the temperature of mercury alloy is in outside the optimum temperature range.For example, in some applications, (sterilization) lamp is necessary can be dimmed, and namely under the condition that is not needing maximum output, the input power of lamp reduces to reduce the output of ultra-violet radiation.In the situation that lamp is dimmed, the temperature of lamp also can reduce.And, using bactericidal lamp to carry out waste water treatment, drinking water disinfection, perhaps when air-treatment, the temperature reduction of water or air can cause that the temperature of lamp reduces.Be somebody's turn to do the position of (sterilization) lamp, namely the horizontal and vertical position of lamp also affects the temperature of mercury alloy.Under these conditions, the Efficiency Decreasing of lamp when the temperature of mercury alloy is lower than its optimum temperature range.
